One of the major challenges for natural language dialog systems has always been the need to respond coherently. This paper examines the relationship between the modeling of intention and the maintenance of dialog coherency for two implemented systems. The main lesson is that developing a proper computational model for intention is absolutely crucial in being able to engage in a flexible and coherent dialog. Furthermore, at some level this model must take into account the expectations of the human conversational partner.
